[HD2 Android Q&A, Help & Troubleshooting and Genera] AgeOfPanic:
That's funny. For months I've been struggling with this issue, until I finally decided that it must be my antenna that is not working correctly. Now it turns out more people have this problem.

I feel that if the signal is strong my NexusHD build has no problem. I walked around yesterday in the center of my town and absolutely no problems. Fast internet, good reception (sometimes even with 0 bars). If you get to an area with weak signal, then the problems start. Frequent disconnects etc. Even if other phones on the same network still have a couple of bars. It could be switching between 3G and 2g or something.
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
Hm, another idea: possible to write a script/fix that automatically try to reconnect to 3g?
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
The odd thing is that when there are 5 bars it doesn't seems to connect but when there are no bars it's fine
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
My understanding is that MAGLDR 1.13 uses RIMNET for Data and not PPP. I'm wondering do you use MAGLDR because I am on T-Mobile USA as well and before I call to make the change wanna see if you are using MAGLDR or PPP?

Man I have A lot of unhappy people. I too have people telling me that their phones have been dropping calls and have terrible service. has anyone tried using a stock ruu from htc to go back to WM to see if they get their service back?
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Odd thing is it's fine in wm6.5 and wp7 but not android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
Weird thing is that I never have dropping calls or terrible service. The connection is fine like you can see in my video. The ONE AND ONLY THING is that any app with push notification or gmail sync doesn't work correctly once the icons switch to grey. So, some script or something must give the command to go grey when....when what???

And why stay grey even when 3g is available?
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Well it seems there are different issues mine for one is that the connection keeps cutting out and i get no service the only way to get it is by selecting the network under mobile network settings.
[HD2 Android Q&A, Help & Troubleshooting and Genera] chdrummerdude:
Ok, has anyone tried calling t-mobile and switich their data plan to the same ones that the android devices use. Or am i over thinking this? I dont recall this happening when ppl were just using haret through WM and loading into android off of their sd.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
I'm using the same plan I use on a native android device although my problems came after flashing clk
[HD2 Android Q&A, Help & Troubleshooting and Genera] Imaginary Enemy:
I've reverted from android to the stock hd2 rom (T-Mobile US). Still no signal. I had signal fine until I flashed nandroid.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Lassito:
I have the same problem. My signal also switch between 0-3 bars. Also my apps who need push doesn't run. I think with my first nand rom from gauner it was ok.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Well I would recommend flashing a previous rom that the signal was fine in and see if there are any differences
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
Yeah, I'm appreciate if any one would try that
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
I called T Mobile and I currently have the standard 30 dollar unlimited data plan they offer on all smart phones and they said there was no difference (TMobile USA)

Funny thing is of I leave it in Edge (2G) only get solid bars all the time and no cellular network loss or bar drop like in 3G

*UPDATE* - I did call T-Mobile USA again but it is always good to get a second opinion and there is infact cellular data plans that differ for Android and Windows but that wasn't the case for me the Data plan I was on was a universal data plan that covered all smartphones ran on T-Mobile minus Blackberry and the old Sidekick. With that said however I guess they have new 3G sim cards and when I got this device it came with the old standard sim cards they were giving out. I have a new card being mailed to me (closed T-Mobile store is 20 miles away and it's not a necessity for me to have 3G) to see if that might correct the issue because the rep said it will help the device connect easier to the 3G network. Who knows but I will update accordingly oh and it is being sent at no charge as well.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Imaginary Enemy:
They told me the same thing when my phone started acting up. I went to the store and got the free updated 3g sim card. It doesn't fix anything.
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Ya I kinda figured it wouldn't do squat but I'm willing to exhaust all options
[HD2 Android Q&A, Help & Troubleshooting and Genera] namila007:
same problem here :D

Sent from my HTC HD 2 powered by HYPERDROID ;)
[HD2 Android Q&A, Help & Troubleshooting and Genera] tageeboy:
Probably the next step to completing the ATT merger is getting new sim cards to users. How long ago did they start offering new 3g cards?
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
No idea but when I called the tech rep said while I see you have an older non 3G sim card so who knows
[HD2 Android Q&A, Help & Troubleshooting and Genera] waynepyrah:
same here... signal dropping regularly on O2 UK
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
So for now I've speak with two more devs of apps using push notification. Both said that there not knowing about this problems with native, original android roms.

And the thing about "new special 3g sim cards" I heard for the first time. I call t-mobile tomorrow and ask about that.

So whatever, seems that these issue really exist only at ported nand roms? Is that for sure or not? Can someone confirm that? maybe ask a friend with an original android phone?

For temporary fix I installed a app that allows only 3g background data. With this my green icons sometimes stay one hour and more. So it have must something to do with switching from active 3g to inactive 3g, but the 3g is still available but it don't reconnect or whatever...
[HD2 Android Q&A, Help & Troubleshooting and Genera] D4rk50ul:
T-mobile us doesn't have special sim cards. Reflash your phone to stock rom. Then hspl 2.08, radio 2.15.50.14, magldr 1.13, cwm 3.0.2.4, copy rom zip using sd reader not magldr, flash rom.

Everything works.

Sent from my HyperDroid powered HD2!
[HD2 Android Q&A, Help & Troubleshooting and Genera] chdrummerdude:
So what your saying is that copying the rom over with magldr is what is actually messing up our data/signal? I have done everything else except that.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Not so much just magldr but, magldr and android cause this for some, the signal and data is fine in wp7. I may try 1.12 later today and see if there is any difference
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
So, maybe any positive results?
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Haven't really had time to test, and will need my phone fully working this weekend so wont have time to test until Monday. Someone could test if they have time. Would be an interesting result if it works.
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
So that "3G Sim Card" did absolutely nothing which I kind of figure after about 2 or 3 hours of running it on the 3G network I lost network connection all together and had to research the network and re-register on the network again to get a connection.

Also during that time the bars were pretty sporadic in signal strength

I just don't understand why if I keep it on Edge or 2G it gets full bars and never drops network but on 3G it does.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Its really odd are you on android nand? If so I think it'll be android related
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Ya I'm running TyphooN CyanogenMod 7 v3.0.3
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
HI

If I remember correctly I used whatever software it's called can't think of the name now that HTC syncs with when the phone is running windows to place my first nand zip file on my phones sd card so I doubt it's a data corruption issue.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Yeah like ive said a few times, it may be android issue because its fine for me in winmo and wp7, if you want you can test for yourself :).
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
Yeah, and like I say a few times before, I think some guys don't get what kind of problem we have?

I don't must "reconnect" my connection cuz I'm don't really "lost" the signal. The signal is almost fine and I can do anything on the internet or market and so on. Only the icons switch from green to grey and all apps who need auto sync (including gmail) or have push notification doesn't sync automatically.

When someone want to flash his rom absolutely fresh than feel free to do so. Then maybe we know more about a magdlr or rom issue or whatever...
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Well there are currently two issues yours with push and sync and mine and others with signal loss, If you want to test try clk and see if you have the same issue if so its android if not its magldr.
[HD2 Android Q&A, Help & Troubleshooting and Genera] thisjustin:
Been following this thread since yesterday because of the issues I have been having with my signal. I've been running typhoon mod 7, magldr 1.13, and radio 2.15. After reading every single post in this thread I decided to flash WP7 to see if there were any signal issues. There weren't. Its great and all that I get better signal or whatever but WP7, IMO, SUCKS!!! (been using android since the g1 was released). So I decided to wipe my phone and go back to android. I wiped my phone and flashed clk this time. I went through everything. Did task 29, flashed CWM, flashed typhoon mod 7, flashed same radio. Results? Same signal issues, 2g works but no 3g.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
I have just tested it with 2g only and its perfect by 3g same thing cuts out and have to re-register network, so it must be an android issue then :S
[HD2 Android Q&A, Help & Troubleshooting and Genera] RuffRap:
yes, but only NAND android. So I think we can do nothing til a developer of a rom figure out what the problem is...
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
My apps sync fine, gmail sync perfectly
[HD2 Android Q&A, Help & Troubleshooting and Genera] thisjustin:
This is not true. Because I have had the same signal problems with both NAND and SD android.
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Signal problems on SD may be and are most likely related to ppp
[HD2 Android Q&A, Help & Troubleshooting and Genera] thisjustin:
oh yeah, thats right
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Another Typhoon user nice I have been trying to get someone in the forum to answer in on the Typhoon Mod 7 forum but no success it just goes unnoticed most times. Hopefully one day a dev will get over here and see this 12 almost 13 pages can't be a coincidence, obviously there is a flaw somewhere sometimes.
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Not saying this is a fix as I just tried it on my phone but I am on H (3G) with full bars and I found it on a search in the Q&A forum so here it goes.

I guess this isn't an option on European models because you can do this within settings but on USA models you can't you have to punch in a code to get it to work

Anyways try this

1- Dial *#*#4636#*#* you will have a menu of testing

2- open Phone information you will see all network info...

3- scroll down and press on set preferred network type..

4- change to GSM AUTO (PRL) .... and done....
[HD2 Android Q&A, Help & Troubleshooting and Genera] M..N:
Has, this fixed your signal problems, I've just done it on my EU hd2 and it seems to be okay :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
It did for awhile but I don't think it's a 100% fix as I woke up this morning and the my was back to no service.

I did stay on 3G for a good 7 or so hours (monitoring) so I'm not sure when it switched to no service but according to my battery usage it said offline for 16 mins so who knows.

I don't know if there is 100% fix for this but guess just keep on trying different solutions out

This was after pulling it off the charger who knows if when it hit 100% battery life is that made a difference ( I doubt it ) but anyways going to let it drain dead and see if it drops it or not
[HD2 Android Q&A, Help & Troubleshooting and Genera] jtwright:
Doesn't that switch you phone to Edge only and eliminate 3G & H?
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
1. Go to your dialer

2. Dial *#*#INFO#*#*

3. Click 'Phone information'

4. Scroll down to the first dropdown selection and set according to your preference below...

For simplicity, there are two main types of cell carriers, GSM and CDMA.

The following popular data communication technology is associated with each cell carrier type:

GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}

CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}

Now that the general stuff is out of the way, here's my take on the Preferred Network types:

WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.

GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.

WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.

GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.

CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.

CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.

EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.

GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)

Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Long story short I think the major issue is the phone is trying to stay on the 3G network and when it can't it just kicks off the network all together and with the default WCDMA preferred that makes sense. This could all just be guessing and I as I said sometime last night my phone clicked off the network but I am up and going to let it drain to almost nothing and see if or how many times it kicks me off the network (percentage wise).
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
No it's good if you have a poor 3G signal coverage area but it does go into 3G as well, not as far as WCDMA preferred but if it's going to hold the network I'd rather get 1.5 mbs most of the day then 3 or 4 mb d/l and have to reset the phone every hour or so.

Still seeing what happens cause as I said sometime last night while I was asleep it did reset
[HD2 Android Q&A, Help & Troubleshooting and Genera] D4rk50ul:
Try a different radio. Depending on location 2.12 and 2.10 were solid choices. Watch battery heat on older radios though. Also try a different rom just incase. Tmobile us has been taking towers down around me but the drop lasts around 3 hours then its fine.
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
I'm on 2.14 now I'll go ahead and try 2.12 because I heard solid reviews on that one 2.15 just seems subpar here. Also what are you APN settings my are as follows

*UPDATE* Signal strength was horrible on 2.12 going to try 2.15 again but it seems as of now 2.14 has the highest level of signal strength for me. You say try 2.10 but there is like 3 of them which one do you choose all and see or is the highest one better?

*UPDATE Part 2* 2.14 still seems to be the best choice for me as far as radio strength

*UPDATE Part 3* It would appear that 2.15 is better after some more testing. I wish I could just get this phone to make up it's mind :)

[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Would changing the DNS settings help with network dropping?? I know it's more for a data disconnect but I figure it might boost the data signal which is what is causing the network disconnect when the network signal drops, just a thought and before I mess with something I never did before I kinda of would like an opinion based on this.
[HD2 Android Q&A, Help & Troubleshooting and Genera] D4rk50ul:
DNS is for translating domain names into ip addresses. Not sure that would have much to do with it.

I have been experiencing the signal bar dropping from full to 2 to none then back up, sometimes no bars for a few minutes at a time, but I am still able to download, text, make calls, even send this reply all with no bars. So to me this isn't a big deal. Only being on this forum 1 day and reading I have my HD2 running Android Gingerbread, so I'm excited to start testing other's
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Well seems like so far keeping it on Preferred Network Unknown is working on pretty good, haven't notice any drop from the network all together as of yet even on GSM AUTO (PRL) it dropped the network after maybe 5 hours or so. I will leave it on over night and see what if when I wake in the morning I still have a connection to the network or not, here's hoping.
[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Okay so I left it on Preferred Network - Unknown all night last night and it didn't drop the network once. I am running Network Monitor to see when and if it drops the network as well when I pushed the red phone button to wake it it was connected to T-Mobile with H as the data network indicator.

So with that said it looks like this has fixed the issue for me at least and I am going to leave it like this for here on out, will update further.

[HD2 Android Q&A, Help & Troubleshooting and Genera] TheCoutures:
Well went about 18 hours till it finally dropped, oh well.

By that time though my battery was pretty low so I don't know if that equates to anything in regards to how much signal strength the radio receives vs when the battery is at a higher charge
